3.1.2PIO_GetConfigAddressSpace

PIO_GetConfigAddressSpace(wBoardNo,*wBase,*wIrq, *wSubVendor, *wSubDevice,*wSubAux,*wSlotBus, *wSlotDevice)

•wBoardNo=0 to N Æ totally N+1 boards found by PIO_DriveInit(….)

•	wBase	Æ base address of the board control word
•	wIrq	Æ allocated IRQ channel number of this board

•wSubVendor Æ subVendor ID of this board

•wSubDevice Æ subDevice ID of this board

•	wSubAux	Æ subAux ID of this board
•	wSlotBus	Æ hardware slot ID1 of this board
•	wSlotDevice	Æ hardware slot ID2 of this board

The user can use this function to save resource of all OME-PIO/PISO cards installed in this system. Then the application program can control all functions of OME-PIO/PISO series card directly. The sample program is given as follows:

/* step1: detect all OME-PIO-D56/OME-PIO-D24 cards first */
wSubVendor=0x80; wSubDevice=1; wSubAux=0x40; /*	for	OME-PIO-
D56/D24 */

wRetVal=PIO_DriverInit(&wBoards, wSubVendor,wSubDevice,wSubAux); printf("There are %d OME-PIO-D56/OME-PIO-D24 Cards in this PC\n",wBoards);

/* step2: save resource of all OME-PIO-D56/OME-PIO-D24cards installed in this

PC */
for (i=0; i<wBoards; i++)
{
PIO_GetConfigAddressSpace(i,&wBase,&wIrq,&t1,&t2,&t3,&t4,&t5);
printf("\nCard_%d: wBase=%x, wIrq=%x", i,wBase,wIrq);
wConfigSpace[i][0]=wBaseAddress; /* save all resource of this card		*/
wConfigSpace[i][1]=wIrq;	/* save all resource of this card	*/
}
/* step3: control the OME-PIO-D56/OME-PIO-D24directly */
wBase=wConfigSpace[0][0];/* get base address the card_0		*/
outport(wBase,1);	/* enable all D/I/O operations of card_0	*/
wBase=wConfigSpace[1][0];/* get base address the card_1		*/
outport(wBase,1);	/* enable all D/I/O operations of card_1	*/
